DISPENS ING DEVICE 3 Sheets-Sheet 5 Filed May 1'7, 1928 Patented Oct. 13, 1931 PATENT OFFICE ROBERT DUNCAN COMRIE, OF SOUTHAMPTON, ENGLAND DISPENSING DEVICE Application filed May 17,1928, Serial No. 278,481, and in Great Britain June 8, 1927.

This invention relates to the removal of powder, crystals, paste, liquids .and like fluid,

semifluid or plastic substances, hereinafter referred to as powder, from containers in regi' ulated ormeasured uantities so as to produce at will a layer substantially uniform thickness of the powder or a desired quantlty of the same which can be taken up by means of a brush, pad, cloth or the like, or be otherwise removed.

According to my invention, there is 'provided, in combination with a container for powder, a band or strip of material which is adapted to receive a layer or quantity of powder on its upper surface and to be moved intothe container tolreceive such charge of powder .and to be withdrawn from such con- 'tainer, so as to bringthe charge of powder 1 into position to permit of its being conveniently removed therefrom by means of a brush or other suitable device. For example, the band or strip can be normally retain ed in'the interior of the container by means of M a-spring, inwhich case the band or strip and the spring maybe formed integrally with one'another of soft vulcanized india rubber. Means may be provided for holding the band or strip in its withdrawn position during the removal of powder.

Thc'band or strip is advantageously provided with a projection which, when said band or strip is in its retracted position, servesto close the aperture in the container through which the band or strip passes, so

Figures 6 and 7 are side elevations of another modification showing the band or strip in its retracted and extended positions re spectively.

Figures 8 and 9 are side elevations of further modifications shown with the bands or strips in the extended position.

Figure 10 is a side elevation and Figure 11 a transverse section on the line XI-XI, Figure '10 showing a still further modification.

In Figures 1, 2 and 3 there is provided within the container A a band or strip B of elastic india-rubber or other suitable mate: rial, which has a suitably shaped cavity C provided with protuberances D, D on its inner surface. The innermost part E of the strip is made thinner, so as to form a spring and extends beneath a bridge piece F in the container, a projection E being provided on the spring piece E to anchor it in the container. The other end of the strip'B extends to the exterior through a slot G in the peripheral wall of the container. The slot G is made of such width as to permit the passage to the exterior of a layer or quantity of powder on or contained by the surface of the band or strip B. The outer end of the strip is provided with an enlarged portion H that normally serves to close the slot and has an extension H adapted to be grasped by the hand. When so withdrawn, the outer end of the strip can be secured on the top of the container by means of a projection J on the container engaging a hole H in the extension H in such a manner that the surface hearing or containing the layer of powder lies over the curved peripheral surface of the container in a substantially horizontal position as shown in Figure 2, so as to en able the powder to be taken off by means of a concave surfaced brush or pad. The en larged end H, H of the strip, which serves both as a closing device and as a handle, may be formed integrally with the strip as shown, or it'may be formed separately and suitably secured thereto. The inner end of the strip may also be clamped between two metal surfaces rivetted together and tea wall of the container, or it may be held in any other suitable manner.

In the arrangement shown in Figures e and the strip is arranged so as to extend substantially-parallel to the upper wall K of the container K at a short distance therefrom, so that. when there is only a small quantity of powder in the container, such powder can be brought by gravity on to such wall, and then'by rapidly inverting the container is allowed to fall on to the elastic band or other material and be drawn ou't'ifor use In this form, the strip B-is drawn out from the container bymeans of a bent leverL pivotally mounted at M on the container K. The facility of removing the last quantity of powder can be increased'by making the container oval in cross-section and arrangmg the band perpendicularjt'othe ma oraxls of" the oval near the curve of smallest radius of curvature. Instead ofusing a band formed wholly ofindia -rubber,"a' band formedpartially of rubber can beemployechthe inside piece of :rubberibeing arrangedrto serve as a springand the outside end being made in thefor m ofa spoon or any othershaped' container, e. 9., of'tin. This may be used as ameasure or device for ensuring regulated deliveries of material.

InFigures. 6 and 7,, the band is extended bymeans ofa metal strip N having an extension O hinged thereto at O'andprOVided with: a finger-piece .P. Suitable guides can bejplovi'dedinthecontainer for the stripN.

Figures ,8. and 9. show modifications where-. in a douhlelband VB is. arranged in two containers Qj/{Q/ and IQ, Q, respectively, having" their: 'lower partsv pivotally connected InFigures 10 and 11, an endless Iband S of-fiexibl'efor elastic material is arranged to extend, over rollers .T, T arranged. inside the :container and over ,a'curvedfsurface V outside the container, a milled head XV being provided for turningyone ofg'the rollers T,

which may be advantageously roughened,ribbed or fluted in such a manner asto engage the band and to bring.parts thereof to the exterior in a convex position in order toiperrent of the powder being conven ently re.-

moved therefrom. If desired,.the roughened,

. ribbed orfluted roller T. may be Imade of larger diameter than the roller T, Y. is a cover hingedto'thecontainer bodyX." V
